This is my second time in this wonderful museum. This time I was accompanied by two friends, and we happened to catch a tour with George, a volunteer, who had the most interesting stories to tell about the early days of the rail road and the coming together at Promontory Summit for the first Transcontinental Railroad. We could have listened for another hour to his wonderful tales and facts, but had to move on to see the rest of the exhibits on the ground floor. Some of the trains are open to walk through - one great one is the dining room with display of the most elegant and precious china. All worthwhile to see.
